During interrogations, the main suspect in the preparation of the explosion at the Cherkizovsky market, Oleg Kostyrev, does nothing but repent. “He is a kind guy, a believer, he was engaged in hand-to-hand combat, a patriot. He prays in his cell, asks for forgiveness,” an operative participating in the investigation tells Newsweek without a shadow of irony. To scare Kostyrev and his comrades did not scare anyone, but they killed at least 10 people.
